PVC-Insulated Formed Copper Busbars for Low-Voltage Switchgear

Custom formed copper busbars with PVC insulation for compact power distribution and circuit-breaker cabinet layouts. Hole patterns, bends, exposed terminal areas, and conductor identification are manufactured according to the approved project drawing.

Challenge

Low-voltage switchgear and power distribution cabinets often contain multiple circuit breakers, protection devices, and connection points within a limited installation space. Conventional cable wiring may require larger bending space, additional terminals, and more manual routing during assembly.

The project therefore required compact copper conductors with controlled hole positions, bend geometry, terminal exposure, and clear conductor identification. The finished parts also needed to fit the cabinet layout consistently without interfering with adjacent devices or required electrical clearances.

Solution

We manufacture PVC-insulated formed copper busbars from C11000 copper or another customer-specified copper grade. Each conductor is cut, punched, formed, deburred, and insulated according to the approved drawing.

Terminal areas remain exposed for bolted connections, while the insulated sections help reduce accidental contact and support organized conductor routing inside the cabinet.

  • Copper grade and cross-section specified by the project
  • Custom hole patterns, bends, and terminal geometry
  • Insulation colours supplied to customer and target-market requirements
  • Controlled terminal exposure for bolted connections
  • Deburred edges and inspected critical dimensions
  • Optional dimensional and material inspection records
The final current rating and insulation coordination should be verified at assembly level according to the cabinet design, operating environment, and applicable electrical standards.

Why Choose Us

Key Advantages

Compact Cabinet Routing

Formed conductors provide a defined current path and require less routing space than multiple high-current cables.

Consistent Installation

Controlled hole positions and bend geometry help the busbars align with circuit breakers and cabinet connection points.

Clear Conductor Identification

Insulation colours and terminal markings can be supplied according to the customer's drawing and target-market requirements.

Drawing-Based Customization

Copper grade, cross-section, hole pattern, bend position, insulation coverage, and exposed terminal length can be customized for the cabinet layout.

FAQ

Frequently Asked Questions

What equipment are these busbars used in?

They are designed for low-voltage switchgear, power distribution cabinets, circuit-breaker panels, motor-control cabinets, industrial control systems, and similar electrical assemblies.

Are these flexible copper busbars?

The products shown are formed rigid copper busbars. If the application requires movement, vibration absorption, or repeated flexing, laminated flexible busbars or braided copper connectors should be considered instead.

What current rating is available?

The current rating depends on copper cross-section, conductor arrangement, ambient temperature, enclosure conditions, terminal design, and allowable temperature rise. It should be confirmed for each application rather than assigned from appearance alone.

Can the busbar shape and hole pattern be customized?

Yes. Length, width, thickness, hole diameter, slot position, bend geometry, terminal exposure, and insulation coverage can be manufactured according to the approved drawing.

What insulation colours are available?

Insulation colours can be supplied according to the customer's identification system and target-market requirements. Electrical labels such as L1, L2, L3, N, or PE should also be defined in the drawing where required.

Does the PVC insulation replace cabinet clearances?

No. The insulation layer helps reduce accidental contact, but it does not replace the required electrical clearance, creepage distance, enclosure protection, or assembly-level verification.

What information is required for a quotation?

Please provide a dimensioned drawing or 3D model, copper grade, conductor cross-section, required current and voltage, insulation specification, terminal finish, quantity, and inspection requirements.
